The MIT MH-850 Shotgun EVO PT speaker cable pair on offer is extremely rare and originally very expensive! OVER $7000 I have never seen one on sale before. Sold here for a fraction of the new price! It was originally developed to replace the Puppy Tails on the Wilson Speakers. It gave such outstanding results, that it became an excellent fit for other speaker/amp combinations. I have used the MIT MH-850 Shotgun EVO PT with my Spectral 360 mono block amps, my Audio Research 600 Mk. III mono block amps and my Soulution amp connected to my Kharma speakers with outstanding results. The sound is very detailed with extended highs, amazing bass, a sweet and textured midrange and a huge soundstage. The cable length is 5ft with the filter boxes connected end-to-end. This is more than enough to connect the amp to the speaker. The filter boxes are incredibly well built of solid metal and pretty heavy. Total weight of all 4 filter boxes is 27kg. All in good condition.
